Skeletons are weak enemies that randomly appear in all areas of the dungeon. While inactive, they are indistinguishable from the harmless piles of bones that may also be found, and will ambush careless Spelunkers that walk over them. It is prudent to always treat piles of bones as if they were Skeletons so as never to be caught by surprise. Undead skeletons lying in wait can easily be dealt with by either jumping onto bone piles or approaching slowly. Within the Jungle and the Ice Caves special caution must be taken as they can be almost invisible depending on the terrain on which they spawn.
